The Trenton Limestone of northwestern Ohio consists of three primary facies: open shelf, platform margin, and platform. The platform margin and platform facies appear to be equivalent to the Point Pleasant Formation. Secondary dolomitization of the Trenton Limestone has resulted in a number of zones and types of dolomite within the unit. A combination of dolomitization models involving shale dewatering and fluid migration along fracture trends are presented to explain the dolomite occurrence.

A thorough understanding of Trenton lithologies, depositional and tectonic settings, and diagenesis should aid future exploration efforts within this once prolific producer of northwestern Ohio.
